The feed contains two sample applications with full support for DSA signature. So you can switch between version 1.0.1 and 1.0.2. In addition to this the 1.0.35 release contains the following new features to be more compatible with the original Sparkle-framework on MacOS X:

Feature: Support of DSA signatures for ultra-secure updates

Feature: Seamless integration—there's no mention of NetSparkle; your icons and app name are used

Feature: UpdateCheck helper for start menu integration

I added also a bunch of documentation pages and sample applications to make the start with NetSparkle as easy as possible
